This tarball contains the maps of the Crab Nebula at 89.189 GHz (HCO+(1-0)
transition) in both temperature and polarization, prodouced from observations
performed at the IRAM 30m telescope from January 9th to January 12th 2009. The
Stokes I, Q and U maps, in Equatorial coordinates, are centered on RA =
5h34'31.5" and Dec = 2201'17.7" (J2000) and have a 10'x6.7' size and a 27"
resolution.  See Aumont et al., 2010, A&A, 514A, 70A for the data processing
and other information

This tar file contains:

* The I, Q and U mapsbuilt by coadding the 28 individual scans listed below,
  and which were used to derive the results presented in Aumont et al. 2010

* The 28 individual RA and DEC scan I, Q and U maps
